Interface
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
template<typename OutputIterator, typename ConstInputIterator>
|
|
static OutputIterator copy(OutputIterator s1, ConstInputIterator s2, std::size_t n);
|
|
|
|
Pre-condition
|
|
========================================
|
|
|
|
| s2 not in [s1,s1+n).
|
|
|
|
Effects
|
|
========================================
|
|
|
|
| For each i in [0,n) performs ``assign(s1[i], s2[i])``.
|
|
|
|
Examples
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
#include <sprout/string.hpp>
|
|
#include <sprout/assert.hpp>
|
|
using namespace sprout;
|
|
|
|
auto x = string<8>("homuhomu");;
|
|
SPROUT_STATIC_CONSTEXPR auto y = string<8>("madocchi");
|
|
int main() {
|
|
char_traits<char>::copy(x.begin(), y.begin(), 8);
|
|
SPROUT_ASSERT_MSG(x[0] == y[0], "y is copied to x.");
|
|
}
|
|
|
|
Complexity
|
|
========================================
|
|
|
|
| linear.
